Looks the same:

dgay at wiseowl:~$ mib510 --rd_fuses
Firmware Version: 2.1
Atmel AVR ATmega128 is found.

Fuse Low Byte      = 0xff
Fuse High Byte     = 0xd9
Fuse Extended Byte = 0xff
Calibration Byte   = 0x00  --  Read Only
Lock Bits          = 0xff
    BLB12 -> 1
    BLB11 -> 1
    BLB02 -> 1
    BLB01 -> 1
      LB2 -> 1
      LB1 -> 1
